There are 3 mayor themes in this tragedy:
LOVE (Obviously): Love is very dominant in this play since the play is centralized in Romeo and Juliet’s passion for each other. Love is a violent and overpowering force that can be clearly observed.
FATE: This indicates that Romeo and Juliet's life could be influenced by some power other than of their wills. There are many events in the play that could have completely changed the outcome of the story.
FAMILY: Both of the families have a lot of influence in this story. It all starts because of a fight of these ones. If this fight didn’t exist, none would’ve been dead at the end and Romeo and Juliet could have been happily married with no one suffering.
